Letters Patent No. 114,244, dated April 25, 1871.

IMPROVEMENT IN COMBINED HARROWS.

Th Schedule referred to in these Letters Patent and maldng part of the same.

To all whom it may concern:

Be it known that I, CORNELIUS WYoKoFF, Jr., of Fairview, in the county of Fulton and in the State of Illinois, have invented a new and useful Convertible Harrow, 't'. c., a har-row whose parts can be changed to make another form of barrow for different purposes; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawing making a part of' this specification, in which like letters of reference refer to like parts, and in which- Figure l represents a plan.

Figure 2, an elevation, (longitudinal.)

Figure 3,..a plan of the saine, altered by change of position of parts to make a follow-barrow for harrowing small grain, whereas figs. l and 2 represent the barrow as a corn-barrow.

This barrow consists i'n so constructing and propor- Vtioning the length of its component parts as to ijt it,

by a slight change of said parts, for either a corn-har row or cultivator or a follower-barrow, for harrowing small grain. In each case the barrow is drawn in a dii'erent direction, so that the teeth are worn in two directions and thus sharpen themselves.

Figs. l and 2 represent the barrow as a corn-harrow or cultivator, of a triangular form.

A A are the two longest sides of the same, each being fitted with the usual teeth or with small shovels, said sides being bolted or screwed to the front crossbar B, the rear ends being separated far enough to allow of their passage along each side of a corn-row so as to cultivate close to the corn. 4

B represents a cross-bar, perforated with holes d fl h h hh h h h It, and is bolted in this case at either end to the top of the side bars A A, the holes It h h h h h h h being for its adjustment to a narrower lWidth ofthe bars A A.

C is a shorter cross-bar, bolted above and to the latter bars, by either end, near their rear ends'.

D is a longitudinal central bar, acting as a brace, and prolonged forward for the attachment to it of the draft, and bolted at its rear end to the middle of' the rear bar C at c c, and to the front cross-bar B at 'd d, and intersecting both bars at a right angle.

It has a hole, b b, for a bolt in its middle part.

Beneath the forward end of this bar, and fastened to it and fitting against the front side of the bar B, is a brace-block, E, through which and the bar D is a bolt-hole, ff, used as afterward stated.

F F are guiding-handles, adjusted to different heights by means of apin and the bolt or pinholes b b b b.

Fig. 3 represents the change of above barrow or cultivator to a follower-barrow for small grain.

The side bars A A, carrying the teeth, are here brought together at their handle ends, and now form the front .of the barrow, the handles remaining in their places, but not used, (in this form of barrow.)

The cross-bar B is moved towardthc center ot' the barrow, and is bolted through either of the holes It h, h b it h. h h, at the option ofthe operator.

The bar O retains its place, not being removed in either form of barrow.

The bar D is reversed, and the draft end, carrying the block E, is bolted through the latter, at f f, into the holes g g now formed by the meeting of the respective half-hole g g of the bars A A. The block raises this end of the bar D, preventing the front of the barrow from being raisedat its point out of the soil by raising the draft.

The central holes b b are now used to bolt the bar C and those at e e to the middle of the cross-bar B.

The harrow is now available for tilling small grain.

'lhe operation of this barrow needs little further description.

It will be seen that the barrow can be gauged, by means of the holes h h h h., a a, 85e., to suit the width of corn-rows, and will barrow the dead-furrow, as well as the hill or ridge, at the same operation.

There are no tenons or morti'ses, and being simply bolted together the machine is rendered easily changeable into either of the above forms by reversing the bar D, and moving the bar B to the holes aY ct a a of the side bars A A, to make the barrow in tin. 3.

That I claim in my invention as new is- 'lhe combination and construction of the bars A A, with their adjustment-holes It h h h a a g` g and their' handles I` F, `with the cross-bar B, with its adjustment-holes b. h h It it h b, h, d d, j f, and e e, and its block E, the cross-bar C, all adjustable to convert the `barrow into either a corn-barrow or cultivator, or into a barrow for harrowing small grain, 85u., as described. In testimony that l claim the foregoing harrow I have hereunto set my hand this 7th day oi March,

A. D. 1871. A
